Fasting and Self-Denial for Spiritual Growth and Sensitivity
Fasting and self-denial are spiritual disciplines that help believers cultivate dependence on Christ and sensitivity to His Spirit. Paul writes in Romans 8:28 that God works all things together for the good of those who love Him, and fasting can be a means of surrendering to this providence. By abstaining from physical needs, believers can focus on their spiritual hunger and thirst, recognizing their utter dependence on God's grace. This practice is rooted in the Reformed understanding of human depravity and the necessity of divine enablement for spiritual growth.
As believers practice fasting and self-denial, they are reminded of their sinfulness and the depths of God's mercy, leading to a deeper appreciation for the gospel. This discipline also helps to mortify the flesh, as described by John Owen, and to walk in the Spirit, as the believer learns to say "no" to selfish desires and "yes" to God's will. In this sense, fasting and self-denial are not ends in themselves but means of communing with Christ and conforming to His image.
The practice of fasting and self-denial is not a means of earning God's favor but rather a way of expressing gratitude for the unmerited favor that has been received through faith in Christ alone. As Charles Spurgeon noted, true fasting is a matter of the heart, and its purpose is to draw near to God, not to impress others. By embracing this discipline, believers can experience a deeper sense of intimacy with God and a greater sensitivity to His leading, ultimately glorifying Him in their bodies and spirits.
